Jack is the most dog loving and caring person I know. He has worked with dogs his whole life and he has a real passion for it. You can see how much he loves dogs immediately when he meets them as he lights right up. He also has a fair amount of "formal" training to work with dogs that need some level of special care and attention. I would fully trust Jack to care for dogs of any breed or temperament. Jack is able to keep up with the most energetic dogs if needed, as he is great shape for physical activity like hiking. I think Jack really excels with dog care, he may be kind of shy with people at first, but not with dogs. He will be the most attentive and loving to your dogs.
